Set in a group of outbuildings on the Grade II listed Stanbridge Mill Farm in Dorset, the Stanbridge Mill Library by Crawshaw Architects in Dorset was originally a cowshed, then used for storage of farm machinery and garden maintenance for over forty years. The new library conversion sits alongside a beautifully converted Georgian farmhouse with a shallow river running beneath a well-preserved water mill.
The library conversion sees a poorly-lit farm building into service as a library and office. While a decisive transformation of the interior was called for, the architect explain that they felt the original use of the building needed to be part of the story.
As such, the high nave and pair of aisles are in the form of a classical library but are set out in the register of the original building using the materials and construction techniques of traditional farm carpentry and metal-work- making possible a degree of analogy between the old and the new uses.
The structural interventions are limited to the removal of two of the original wooden trusses which have been replaced with laminated wooden portal frames to stabilise the external walls and to make way for the barrel-vaulted nave. Three new conservation-style roof lights interrupt the vault to provide natural light to the book-stacks. The floor in the library has been partially dug out by hand and lowered by two feet.
The vault, columns, shelves, tables and seating are made of the same solid oak planks and sections, deliberately selected to show knots and natural blemishes, and assembled using simple traditional socketed carpentry. The new internal doors and windows match the existing black steel-framed external windows. All the fittings are contemporary but closely related to the original iron frames and fixings.
The re-purposing of the existing shell using a wooden structural intervention and natural insulation materials combine to make this project highly sustainable.
